This invention relates to .an improved check strap for looms which hasoverlapped ends at one or both ends thereof so as to give double wearingqualities and at the same time permits the :use of shortpieces-ofleather, whereas heretoiore check straps have been composed of one longpiece of leather which is very expensive because only asmall portionof'a cowhide has leather of suiiicient thickness and length to .pro-

-vide the "elongated strips which have heretofore been in conventionaluse. By "the use of short pieces of leather and overlapping the same atone or both ends, a check strap can he provided which will "havemuchlonger wear than the conventional check strap made of one long piece ofleather but will be much less expensive on account of being able to usea large portionof the cowhide which .hereto'fore has been unsuitable foruse as check straps.

'It is an object of this invention to provide a check strap for loomsmade of a piece .of leather overlapped at one orboth endstoprovideadouble thickness .of wearing surface at the point wlhere thepickerstick .engagesthe check strap.

It is another object of this invention to. provide a check strap .madevof two pieces of leather and overlapping at :one of the ends and aneccentric wearing plug, preferably made of leather, vdisposed betweenthe other ends so that the eccentric wearing plug can be adjusted as toposition to regulate overall length of the interior portion of the checkstrap from one end to the other.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings in which Figure 1 is a side elevation of oneend of the lay of a loom showing my invention applied thereto;

Figure 2 is a bottom plan view, partly in section, looking upward frombelow Figure 1;

Figure 3 is a view similar to Figure 2, but showing the check strap ofdouble thickness;

Figure 4 is 'a view similar to Figure 1, but showing another" form ofcheck strap;

Figure 5 is a bottom plan view looking upward from the lower edge inFigure 4;

Figure 6 is a view similar to the structure of the check strap shown inFigure 5, but showing it of double thickness.

Referring more specifically to the drawings the numeral l0 indicates oneend of the lay of a loom having a race plate H and box front l2, therebeing a binder also on the top of the plate ll,

straps 3.0 and 3|.

but this binder is behind the box front and isnot shown, and betweenthebinder and "box'iront I2 a shuttle I3 is adapted to be received tocause its :nose "to strikeraupicker I' l disposed on an oscillatingpicker stick iii, which has back and forth movement in a slot H in therate plate ll. J Secured to the lower and side surfaces of the lay i0and on each side of the slot I! are the brackets 20 having a pair ofdownwardly projecting spaced fingers 2! and -22 and this bracket hasouttunned lips :23 having a slot '24 therein penetrated by a bolt 25towhich is adjustably secured a horizontal portion .26 of a downwardlydepending finger 21, the'fingers 2| and .22 and 21 having in'turnedlipsat their lower ends for holding the check strap in its elevated positionand the off set relation of fingers 2|, 2], and "22 imparts the properamount .of friction to the longitudinal .movement of the check strapwhen stopping the picker stick as it oscillates or swings in bothdirections. The above described mechanism is conventional in a loom andit is with such a mechanism that my improved check strap is adapted tooperate.

My improved check strap comprises -a pair of .short pieces of leather 0and 3 which are overlapped at one end as at 32 and '33 and securedtogether by anysuitahle meanssuch as rivets 3B.

gives a double wearing portion to the overlapped ends of the checkstrap. Between. the other ends of the straps 3B and 3! there is securedan eccentric block 35 by :means of a bolt 36 and if desiredsuitab-lepieces of leather 3'! and --38;beveled at their inner ends may bedisposed between the eccentric 35 and the ends of the These are securedin position by any suitable means such as rivets 39.

In Figure 3 a slightly modified form of invention from that shown inFigure 2 appears, which has the same structure as the interior portionof that above described but has additional straps 40 and 4| which areoverlapped at one end as at 42 and 43 and the rivets 34 are longer thanin Figure 2 so as to penetrate the four layers 32, 33, 42, and 43. Theform in Figure 3 is better adapted for heavy work as it gives a fourplyconstruction at the inner end of the check strap.

In Figures 4, 5, and 6 a modified form of invention is shown which hasthe same construction at the left hand end as that shown in Figures 1,2, and 3. The check strap in Figures 4 and 5 comprises straps 50 and 5|overlapped atboth ends as at 52, 53, 54 and 55 and secured together byrivets 56. In Figure 6, the inner straps 50 and 5| are the same as inFigure 5, but it has an end portion strap' is engaged by a picker stick;

outer straps 57 and 58 which are overlapped at their ends as at 59 and60 at one end, and 6| and 62 at the other end and longer rivets 56secure all overlapped ends together. In Figure 6, it is therefore seenthat a strap of double thickness on the sides and quadruple thickness atthe ends is provided. This not only gives very thick and long lastingwearing portions, but it is to be especially noted that in all forms ofthe invention short pieces' ofleather can be utilized instead of thelong, rare andexpensive pieces of leather heretofore used.
